Creating Logging Plug-ins
A logging plug-in is an event notification plug-in that handles event notices raised by the server when the server logs client activity. Typically, the client is a distribution server, a cache proxy server, or a player. When you create a custom logging plug-in, you can retrieve client information and publish it to a file, a Web page, the Windows Event Viewer or any other delivery vehicle that serves your purpose.
Logging plug-ins can be installed at both the server level and the publishing point level. A logging plug-in installed at the server level receives every notification of every requested event that occurs. A logging plug-in installed at the publishing point level receives notification of requested events related only to the publishing point.
The following sections discuss custom logging plug-ins in detail.
